When Marshall Henderson was pulled over for speeding in early May, officers found small amounts of marijuana and a trace amount of what appeared to be cocaine, the Wall Street Journal reported, adding further circumstantial evidence that the Ole Miss guard is dealing with substance-abuse issues.

Henderson was jailed in early 2012 for violating terms of his probation. He had failed tests for alcohol, marijuana and cocaine.

Because Henderson was found with less than one-tenth of a gram of what was thought to be cocaine, the police report indicated the prosecutor’s office would not prosecute it, the Wall Street Journal noted.

Henderson also has been known to post on Twitter #whitegirlwednesday, which could be a veiled reference to cocaine. White girl is slang for the drug.

Henderson said on Twitter on Thursday that he’s not going anywhere, and he has spoken with Chris Herren, a former NBA player whose own substance abuse issues became widely known after he penned a book about his experiences, and his story was featured on ESPN's "30 for 30" series.

Henderson remains on suspension by the school, and sources told CBSSports.com that his status with the team is in doubt.
